10 Claims.

machines illustrated in these patents are such that on any operation involving an automatic carriage return with clearing oi the set bars, all the locking slides of both upper and lower zones, which had their associated interponents set in active positions, were retracted. For example, operation of the CanceL Trip, or Trip intermediate stop key of the machine disclosed in Patent 2,124,178 caused an automatic carriage return and clearing in both upper and lower zones of the set-bar section of the punch. The

present invention permits the punch operator to select any one of three methods of clearing the set bars. First, when using the Intermediate stop, he may set the machine so that, on carriage return and clearing operations, only the upper zone will be cleared. Second, he may set the machine so that, on carriage return and clearing operations, only the lower zone of the set bar section will be cleared. Again, he may set the machine so that it functions, as is disclosed in the above patents, to clear both upper and lower zones at once. The machine also functions to clear in both zones of the set bar section when the intermediate stop is positioned on the machine but not in use, that is, when the trip key or cancel key is operated. These two keys render the intermediate-stop engaging-lug on the carriage ineffective as is old and well known. Thus, it is seen that the present invention lends great eXibility, on clearing operations, to the punch. It is particularly useful with certain accounting systems where it is found desirable to leave certain data in either the upper or lower zone for a plurality of punching cycles.

The main object of this invention is to enlarge the scope of punching machines with respect to the clearing of data set-ups made in those machines.

Other objects and structural details ofthe nl vention will be apparent from the following description when read in connection with the accompanying drawings, wherein y Y Fig. 1 is a fragmentary front elevation of the machine;

Fig. 2 is a fragmentary sectional elevation showing the carriage, the set bar section and the punch section of the machine;

Fig. 3 is a fragmentary, elevational deta1l of the carriage and set bar clearing mechanism; and

Fig. 4 is a diagram showing all circuits necessary to an understanding of the present invention.

Referring to Fig. 1, a motor generator I is employed to supply current for operating the machine. In addition, it is used to rotate the main shaft 3 through reduction gearing 2. Shaft 3 carries magnetic clutches 4 and 5 which clutches,

when operative, couple the main shaft 3 with the back space mechanism and the carriage return mechanism, respectively. The Vexact construction of these clutching devices will not be described here as it is old and Well known. Suice -it tosay that a trip magnet 5, when energized, withdraws a blocking nger 8 from the path of a clutch pawl 9 vof a single revolution clutch, thus coupling the main shaft 3 to a sleeve II upon which the large lreduction gear 2 is fastened. The ring magnets of clutches Il and 5 are also fast to sleeve Il. Thus, if either clutch II or 5 is energized, their ring magnets will engage their associated armatures to operate either the back space mechanism or the carriage return mechanism. Clutches 4 and 5 are entirely independent of the single revolution clutch, so that the main shaft 3 need not be rotated to effect back spacing or carriage returning. For specific details of this structure, reference may be had to and lower the card and punch frame and rotate certain control cams, as is old and well known, to effect punching of a card The meansv employed for entering set-ups into the set bar section of the punch is the same as was previously used and will be described only in brief here. As can best be seen in Fig. 1, keys I2, when depressed, close contacts (not shown) to energize solenoids I3, the cores of which, in turn, actuate Bowden wires Iii to rock bell-cranks I5 (Fig. 2), causing depression of links I6. Bellcranks I5 and links IB are mounted in a carriage I'l which, :as is well known, travels step-by-step over the columns of pins 29 in the set bar section of the punch during setting-up operations. Referring particularly to Fig. 2, the depression of links I6 causes depression of set bars I9. The set bars are held in depressed position by locking slides 29 under the action of leaf springs 2|, as is old and well known, alternate locking slides being used to lock the set bars of both upper and lower zones. In the position shown in Fig. 2, the locking slides 29 are retracted allowing clearing of the set bar section.

Previously, the locking slides 20 were retracted, during machine operations which included carriage-return with clearing, by the action of a single retract solenoid which, through a Bowden wire, actuated a bell-crank 23 to lower a roller 24 into contact with interponents 25. The return of the carriage caused the roller 24 to push locking slides 2D seriatim to the inactive position shown in Fig. 2 to release any depressed set bars |9 and allow them to return to their upper or normal positions under action of their associated springs. Thus, before the present invention, any interponent 25, which was moved by roller 24, disabled its associated locking slide 29 during carriage-return and clearing operations. All the interponents were in alignment insofar as their surfaces 26 were concerned so that, during a clearing operation, if the carriage returned ten steps, ten interponents were actuated which, of course, resulted in clearing both the upper and lower zones of those columns of the set bar section concomitantly.

The mechanism of the present invention includes tWo retract solenoids of which, when actuated, lowers the old roller 24 to active position for clearing and the other of which lowers a similar roller 21 for the same general purpose. Now, however, every other interponent is shaped like the interponent 25 but the alternate interponents 28 have such shapes, shown partially in dotted lines in Fig. 2, that the roller 24 never actuates them. These interponents 28 are actuated only by roller 21 to release the set bars I9 associated with the upper zone of the set bar section while the interponents 25 are now associated only with the lower zone.' Thus, if it is desired to release the set bars in the upper zone, the. upper retract solenoid is energized and, if it is desired to release the set bars in the lower zone, the lower retract solenoid is energized. To release the set bars in both zones concomitantly, both retract solenoids are energized and both rollers 24 and 21 are lowered. Referring to Figs. 2 and 3, roller 21 is carried by an arm 30 which is pivoted upon the carriage l1 at 3|. The arm 39 is connected to the lower end of a link 32, the upper end of which is connected to a rock lever 33 at 34. Rock lever 33 is pivoted at 35 upon the carriage |1 and is guided in a comb plate 36 which plate is part of carriage I1. One end 38, of lever 33, rests against a Bowden wire terminal 39. A Bowden wire 40, one end of which is secured in the terminal 39, is fastened, at its opposite end, to the core of the upper retract solenoid 4| (shown only in Fig. 4). Thus, it is seen that, upon energization of solenoid 4|, the Bowden wire 49 is moved to swing lever 33 counter-clockwise (Fig. 3) to depress link 32 and lower roller 21 to active position. In like manner, energization of the lower retract solenoid 42 (Fig. 4, only) will move a Bowden wire 43 (Fig. 3) to lower roller 24 by means of well known mechanism.

Circuits Referring to Fig. 4, all the circuits necessary to an understanding of this invention are shown, in a schematic manner for the sake of clarity. Starting at the positive terminal of generator current passes over lead 49 to an on-off switch 45, thence to a repeat-single switch 46 and thence to a main supply lead 41 as is old and well known. A branch 48 of lead 41 supplies power to a timing device T by means of a brush A. This timer is a drum commutator shown developed and is exactly the same as has been used in previous machines and it is mounted upon the main shaft of the machine. This timer is also shown in Fig. 4 of the above mentioned Patent 2,124,178, to Lasker. Every time the main shaft of the machine turns, the timer T rotates with it. Current is supplied directly by lead 41 to a trip key 50 and a trip intermediate key 5| but is supplied to a cancel key 52 through the timer T as will now be described in detail.

Cancel key When the cancel key 52 is depressed, it accomplishes the following functions:

l. Return of the punch carriage.

2. Clearing of part or all of the set bars.

3. Preventing rotation of main shaft 3 which, consequently, prevents card punching and card feeding. i

The mode of operation of the cancel key 52 and its associated parts is as follows: When key 52 is operated, contacts 54 are closed, providing a circuit from positive supply lead 41, through the winding of relay 51, over lead 58, through contacts 54, lead |50, brushes F and E of timer T, lead I5I, winding of carriage return magnet 59 and lead 53 to the negative generator terminal. This energizes relay 51 and magnet 59 and attracts armature 60, which, in turn, moves latch 6| counter-clockwise about its pivot 62 to release bell-crank 63 pivoted at 64 (see Fig. 4). Bell-crank 63 (see Fig. 1) is loosely connected by a stud 65 to the stop bar 66 of the machine. This bar 66, as is well known, carries a margin stopA 61 and an intermediate stop 68 and, on carriage return movements, a lug 69, controlled by the express solenoid, strikes one or the other of the stops to shift bar 66 to the left (against spring tension) and thus restores the bell-crank 63 to its normal position shown schematically in Fig. 4.

Whenever the carriage return magnet 59 is energized with the resulting movement of bellcrank 53, contacts 1| and 12 are closed and they remain closed until the carriage, in returning,

, restores bell-crank 63 to its normal position. The

closure of contacts 12 eiects a return movement of the carriage by energizing ring magnet 5 (see Figs. 1 and 4), over the following circuit: From positive generator over supply lead 41, lead14, through the ring magnet or magnetic clutch 5, overlead 56, through contacts 12 and lead 53 to the negative side of the generator. Carriage return magnet 59 is deenergized as soon as the cancel key 52 is opened, but it is unnecessary for the operator to hold the cancel key closed for contacts 12 remain closed, as has been explained, until the carriage has completed its return.

It will berecalled that the retract relay 51 is also energized by cancel key 52 and it is held operated over a locking circuit traced as follows: Positive current over lead 41, through the winding of relay 51, make contacts 15 of said relay, and lead 16 to the contact Vl of a double-pole, double-throw reversing switch l5. Contact 'H is connected to a contact 19 on the said switch and, in like manner, a contact 8| is connected to a contact 82. Switch arms 83 and 84 are insulated from each other. Thus, it is seen that, when current enters at 'i7 and the switch 18 is set in its left-hand position, the current will flow directly into arm 83 and out therefrom along lead 35 to upper retract solenoid 4|, thus actuating the retract roller 21 (Figs. 2 and 3). The current continues from retract solenoid 61|, along lead 8l and through contacts to the negative side of the generator over lead 53. If, however, the switch 18 is set in its right-hand position, then current flows from contact 'l1 to contact i9 to arm 84 and out over a lead 89 through the lower retract solenoid 42 and thence over lead 81 to the negative side of the generator through contact 1| as described. The operation of solenoid 42 causes the retract roller 24 (Figs. 2 and 3) to be lowered to active position for clearing the lower zone of the set bar section. Thus, it is seen that switch 'I3 is a reversing switch and can be set to run current from contact TI to either the upper or the lower retract solenoid. In like manner, when current is supplied to contact 8|, the switch 'I8 may be set to pass the current either via arm 84 to lead 85 or Via contact 82 and knife 83 to lead 8E. It is to be noted that, if current is supplied concomitantly to both contacts Tl and 8|, then both retract solenoids will be energized concomitantly and clearing will occur in both upper and lower set bar zones during a single carriage return. This double supply of current can be brought about either by closing a single-pole single-throw switch 9| or by permitting current to ilow through the contacts l5, on the retract relay l to contact 'Il over lead 75 and also from' contacts 'l5 and lead'55 to break contacts 52 (normally closed) on a trip intermediate relay 93, over a lead 94 to switch 9| and contact 8| of switch '18. When the cancel key 52 lis operated, the trip intermediate relay is not operated and hence clearing occurs in both zones of the set bar field regardless of the setting of switch 18 or switch 9|. In this instance, the carriage will be returned to the margin stop El (Fig. 1) because of the action of the well known express solenoid 96 (Fig. 4). The express solenoid,.as can be seen operates over a circuit from the positive side of the generator through the onoff switch, repeat-single switch 55 over lead 47 and thence through an intermediate-margin switch 98, over lead 99 through contacts IUI' of the trip-intermediate relay 93 and thence over lead |02, through the express solenoid, lead |83, through carriage-breaker contacts |54 and over lead 53 to the negative side of the generator. When the carriage, at the end ofvits return movement, returns the bellcrank $3 to normal, it has a slight overthrow which results in momentarily breaking contacts HM and in normalizing an electro-magnetic device, which is operated from the negative side of the gen- L erator over lead |53. With regard to the margin-intermediate switch S8, this is shown set in the margin position in Fig. 4.- If, however, the switch is set in the intermediate position, the contact between the supply lead 4l and lead SS is broken and power can be supplied to lead 99 only through the medium of a trip relay H3, the operation of which will later be described; It is to ber understoodlthat whenever. the express solenoid is ,energizedVits core acts through well known mechanism to raise the stop block 59 (see Fig. l) to a position above the intermediate stop 58 so that, on carriage returns, the carriage will pass on by the intermediate stop 68 and come to rest against the margin stop 6l. As the switch is set in Fig. 4, it shows this condition but when it is desired to stop the carriage at an intermediate position, switch 98 is. thrown to the left breaking its contacts and hence breaking the positive lead Q9.

Trip key When the trip key 55 (Fig. 4) vis operated, it

results in effecting the following machine functions:

1. Rotation of the main shaft through one revolution.

2. Return of the carriage to the margin stop regardless of the setting of the margin-intermediate switch 98.

3. Clearing in both set bar zones regardless of the setting of switches 'i8 and 9|.

4. Punching and ejecting of a card.

5. Feeding a new card into the punch charnber.

Theexact manner in which these functions are performed will now be described. When trip key 55 is operated, both of its contacts |59 and ||El are closed (Fig. 4). Closure of contacts lll) closes a circuit from positive generator over lead 49 through switches 45 and 45, over lead lll, through contacts H, over lead H2, through the winding of a trip relay AH13, over leads HI and |63, and thence through carriage breaker contacts llll to the negative generator terminal, over lead 53. This energizes relay H3 causing closure of its contacts H4 and H5. Contacts H5 close a holding circuit for the relay which is traced to positive generator over lead 4l. The relay will remain energized until the overthrow of the returning carriage breaks contacts lill?. Contacts IM (thus closed) establish a circuit which may be traced as follows: From the positive generator terminal, over lead 49, through switches l5 and 43, lead 47, contacts H5, leads H7 and 99, contacts |ll| of relay S3 through the winding of the express solenoid 96, lead |53, breaker contacts |511, lead 53 to negative generator. This energizes the express solenoid regardless of the setting of the intermediatemargin switch 98.

Closure of contacts |55, on key 5i), establishes acircuit for energizing the trip magnet 5 which may be traced from positive, lead il and 43, brush A, segment lit of timer T, brush C, lead H9, through contacts |59 of key 5|), lead |20, through the winding of trip magnet t to the negative generator terminal over lead 53. This energizes. the trip magnet which results in a single revolution of the main shaft as was previously explained. Movement of the main shaft 3 (Fig. 1) results in punching a card and in feeding a now one into the punch chamber as the punched card is ejected therefrom. Rotation of main shaft 3 also causes rotation of the segments of timer T. It is thus seen that soon after the main shaft begins to rotate, brush C falls away from segment I8 so that even if the trip key were held down it could not supply current to the trip relay H3. It would be unnecessary inview of the described holding circuit through contacts H5..k

-" Near'the end of the rotation of the main shaft,

carriage a segment |22, of timer T, cornes under the brushes D and E. This establishes a circuit for clearing and returning the carriage which may be traced from positive lead 41, lead 54, through the winding of retract relay 51, over lead 58, through brush D, timer segment |22 and brush E overlead |5I, through the winding of carriage return magnet 59 and over lead 53 to the negative generator terminal. The energizing of carriage return magnet 59 and retract relay 51 causes energization of both retract solenoids 4| and 42 resulting in clearing in both zones of the set bar section.

There remains but one key to be described. This is the trip-intermediate key 5|, and it is with this key that the reversing switch 18 comes into play. Switch 18 when used with the trip- -intermediate key permits selective clearing operations as will now be described in detail.

Referring to Fig. 4, key 5| has two contacts |23 and |24. Closure of contacts |23 establishes a circuit traceable from positive lead 41, contacts |23, leads |26 and |20, through the winding of trip magnet 6 and over lead 53 to negative generator. This energizes the trip magnet 6 to start the main shaft rotating.` Closure of contacts |24 establishes a circuit traceable from positive lead 41, contacts |24, lead |21, winding of trip intermediate relay 93, llead |03, contacts |04 of the carriage breaker switch, and lead 53 to the negative side of the generator. This energizes the trip intermediate relay S3 which results in opening relay contacts 92 and |0| and closing a pair of contacts |28. Contacts |28 then form part of a holding circuit for the trip intermediate relay H3, current being supplied from positive lead 41 through a lead |29 through Contact |28 and winding of the relay to negative current as described above. Opening of contacts |0| causes the express solenoid 9S to be deenergiZed so that the carriage will return only to the intermediate stop S8 (Fig. l). Lastly, opening of contacts S2 breaks the circuit through lead 94 to contact 8| on the reversing switch 18. Thus, current may only be supplied to the reversing switch, at a time when the retract relay is energized, through lead 1,3 to contact 11. Under these conditions, if the reversing switch is set in its left-hand position, current is supplied from contact 11 through arm 83 to the upper retract solenoid 4| and, if the reversing switch is set in its righthand position, current is supplied from contact 11 to contact 19 and thence through arm 84 to the lower retract solenoid 42. Energizing of the retract relay 51 and the carriage return magnet 59 is accomplished the same as when the trip key 50 is actuated, that is, by rotation of timer T to bring segment |22 Linder brushes D and E.

From the foregoing, it is seen that current is supplied to the retract solenoids by actuation of the retract relay and that actuation of this relay without actuation of the trip intermediate relay will supply current to both retract solenoids simultaneously through leads 16 and 94. When, however, the retract relay is operated with the trip intermediate relay, the trip intermediate relay breaks lead 94 and permits the reversing switch 18 to be operated to select one or the other of the retract solenoids. W'hen using the trip intermediate relay, the express solenoid is always disabled in consequence of which the carriage comes to rest against its intermediate stop. In this connection, it is to be noted that the intermediate stop 68 (Fig. l) can be moved far enough to be left to permit a carriage travel that mi would allow clearing of an entire zone of set bars.

It is also to be noted that should the need arise for punching a plurality of cards with one set up, the reversing switch 18 provides an additional means for satisfying it. If the switch arms '83 and 84 are set in a middle position, wherein they do not contact any of the points 11, 8|, 82, and 19, then operation of either the trip or trip-intermediate keys will cause a punching and ejecting cycle with a carriage return but `without erasing any of the set up in the set bars because no current passes from the reversing switch to the retract solenoids.

Should it be found desirable to have the punch function as it did before the present invention, then the single-pole single-throw switch 9| is closed and this enforces concomitant clearing in both set bar Zones even when the trip intermediate relay is operated and regardless of any active setting of the reversing switch 18.
